i just got the same clamps today from ebay..i was very please with the craftmanship..although there is a spot or 2 of the powder coat not pristine..
i showed them to a customer of mine today, he suggested lining the inside with some thin rubber from a tire tube etc...to make a tighter clamp and prevent rubbing..also to put some lubricant on the allen screws to keep them from rusting out..
i ordered 2 more sets...just they looked awesome for the price..
